摘　　要：为了解决互联网中的远程主机和车载系统网络互连的问题,设计并实现了一种IPv6-CAN双协议转换的车载网关。通过在车载网关中对CAN节点设备的虚拟化,并为每个虚拟化的CAN节点分配IPv6地址,使得远程主机可对CAN节点进行操控。并且由于IPv6的使用,统一了远程主机对CAN节点的访问方式。通过对CAN总线访问方式的改变,将传统的以文件读写方式访问的CAN设备驱动改写成为网络设备驱动程序,极大地提升了此类网关的性能。最后的实例结果表明了该方法的可行性。To solve the net-connection problem between remote entity and vehicle system, a kind of gateway is designed and implemented which can switch protocols between IPv6 and CAN. The CAN entities＇ equipment in the vehicle＇ s gateway is simulated and an IPv6 address is distributed to each virtualized CAN entity, so that the remote entity could operate the entity. Since the application oflPv6, the methods of remote entity accesses CAN entity are consolidated. According to the change of the access method of CAN bus, the CAN equipment driver with traditional access method by reading and writing files is replaced by the net equipment driver, which promotes the gateway＇ s capability extremely. Finally, performances of the proposed method are demonstrated by the application.
